Abstract

To operate a twist-stabilised burner using a gas or liquid fuel, and especially as a premix burner, lighting-up air (38) is injected during the lighting-up process, at the downstream end of the twist generator (37) from the edge to the centre. The injected air has at least one radial speed component. After lighting-up, the injected lighting-up air stream (38) is stopped. The burner may have at least two units (40) at the downstream end of the twist generator (37), for at least a partially radial injection of lighting-up air (38) against each other. They are connected to feed lines (41), which can be closed selectively.
